Hey i need help on this question even if you can only answer one of the three boxes but if someone can do 2 or more that would be very apricated

thanks!

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

At your job you're paid $50 per week plus $3 per sale at least how many saled do you need to make in order to have over $250

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
